My Lords, these regulations will bring in new alcohol limits for professional mariners in UK waters or serving on board UK-flagged ships wherever they are in the world. These limits, more restrictive than those in place today, are aligned with those agreed at the International Maritime Organization to apply to all shipping around the globe, with the intention of improving maritime safety.
Noble Lords will be aware of the vital contribution made by the maritime industry to the well-being of this country. In this London International Shipping Week we are celebrating the fact that 95% of our imports and exports are carried by ship, and that the maritime sector contributes up to £13.8 billion of direct gross value added to the UK economy each year. It is therefore crucial that we seek to ensure the safe operation of this industry, working with shipping and port operators and with other maritime nations around the world. One source of risk that we can tackle together is that posed by alcohol consumption, which can impair the ability of mariners to fulfil safety-critical duties.
On the roads, a driver with 100 milligrams or more of alcohol in 100 millilitres of blood is seven times more likely to be involved in a fatal motor vehicle crash than is a driver who has not consumed alcohol. If the amount of alcohol is 150 milligrams or more, it is roundly 25 times more likely. The same underlying principle applies on a ship; excessive alcohol consumption increases the risk of error and accident. The current alcohol limits for professional mariners were introduced by the Railways and Transport Safety Act 2003 and are the same as those applied to motorists in England and Wales—in the case of breath, 35 micrograms of alcohol in 100 millilitres; in the case of blood, 80 milligrams of alcohol in 100 millilitres; and, in the case of urine, 107 milligrams of alcohol in 100 millilitres.
At that time, there was no internationally agreed alcohol limit for mariners. This situation changed in 2010, when the Standards of Training, Certification and Watchkeeping Convention of the International
Maritime Organization was amended. For the first time, mandatory alcohol limits for mariners globally were agreed—in the case of breath, 25 micrograms of alcohol in 100 millilitres, and, in the case of blood, 50 milligrams of alcohol in 100 millilitres. These regulations will bring UK legislation into line with the alcohol limits agreed internationally, with the addition of a limit in the case of urine of 67 milligrams of alcohol in 100 millilitres. In doing so, we will reinforce the importance of these limits in securing the safety of ships, and all those who travel on them.
Furthermore, having common international limits helps to ensure that mariners know what is expected of them wherever they are, and enforcement when people are found to have exceed those limits, national borders not being visibly marked at sea. The regulations also require the Secretary of State to review the impact of the amendments they make and publish a report of the review’s conclusions. This provision seeks to ensure the continued effectiveness of the alcohol limits set for professional mariners for the long term. Her Majesty’s Government are committed to maintaining safe navigation around these shores and, indeed, wherever ships registered in the UK may sail. These new limits on mariners’ consumption of alcohol are an example of how we are doing this in co-operation with our international partners. I commend these regulations to the Committee.
